A disappearing act was the last thing Rice University physicist Randy Hulet expected to see in his ultracold atomic experiments, but that is what he and his students produced by colliding pairs of Bose Einstein condensates (BECs) that were prepared in special states called solitons.

Hulet's team documented the strange phenomenon in a new study published online this week in the journal Nature Physics.
